In-situ preparation of MIL-88A(Fe)/MIL-100(Fe)/PVA-Co-PE nanofiber membranes for efficient photocatalytic reduction of CO2

Abstract

In this paper, we tend to ready a polyvinyl alcohol-polyethylene (PVA-Co-PE) composite nanofiber membrane catalyst decorated by bimetallic organic framework MIL-100(Fe)/MIL-88A(Fe). The experimental results of the performance of photocatalytic reduction of CO2 show that it exhibits glorious photocatalytic activity for the reduction of CO2 underneath actinic ray irradiation, and also the best conversion rate of CO2 is 8.3 mL/h. Through SEM, XRD, BET, DRS, FTIR, and alternative characterization ways, the factors touching the photocatalytic CO2 reduction method of the composite nanofiber membrane were investigated. Studies have found that the bimetallic framework structure increases the photocurrent density and significantly reduces the photoluminescence intensity. The versatile composite nanofiber membrane has high photocatalytic activity and smart reusability and features a smart prospect within the photocatalytic reduction of CO2 treatment.
